Electrical DN as an Adjunct to Eccentric Exercise, Stretching + MT for Achilles Tendinopathy

This study tests whether adding electrical dry needling (EDN) — a technique where a fine needle is inserted into muscle tissue and combined with mild electrical stimulation — improves outcomes beyond standard physical therapy for people with chronic Achilles tendinopathy. Achilles tendinopathy is a painful, often persistent condition affecting the tendon connecting the calf muscles to the heel bone, common in active adults. Participants have had Achilles pain for at least 3 months and are randomly assigned to receive either standard therapy alone (eccentric exercise, stretching, and manual therapy) or the same therapy plus electrical dry needling. The study tracks pain, function, and recovery over time. You may be eligible if: - You are an English-speaking adult over 18 years old - You have had Achilles pain for at least 3 months, clinically diagnosed as Achilles tendinopathy - You have not had physical therapy, massage, chiropractic care, or injections for Achilles pain in the last 6 months You may NOT be eligible if: - You have diabetes, peripheral neuropathy, heart disease, or other serious medical conditions - You have had previous Achilles tendon surgery or ankle fusion - You are pregnant - You are involved in workers' compensation or litigation related to foot pain Talk to your doctor to see if this trial is right for you.
